IMPROVEMENT IN APPARATUS FOR DISTILLING.

Specification forming part of Letters Patent No. 128,291, dated `lune 25, 1872.

Specification describing a new and Improved Distilling Apparatus, invented by HEINRICH DRDDIG, of Brieg, Prussia.

Figure 1 represents a vertical central section of the mashing apparatus and column. Fig. 2 is a vertical central section of the condenser and cooler. Fig. 8 is a diagram, showing all parts connected. Fig. 4 is a detail horizontal section of the cooler taken on the line c c, Fig. 2.

This invention relates toa new distilling apparatus, which has for its object to obtain the largest practicable yield of spirits in the shortest time from a given quantity of mash, and consequently to be more economical in its operationthan the devices for the same purpose now in use. The invention consists in a new arrangement of mashing apparatus, rectifyingcolumn, condenser, and cooler, all as hereinafter more fullyr described.

The apparatus a toto consists of four principal parts-the mash apparatus A, rectifying-column B, condenser C, and cooler D- they being represented as properly connected in Fig. 3. The mashing apparatus A, shown in Fig. 1, is a cylindrical upright vessel, having a series of transverse partitions, a a, which form a lower mash-collector, b, a number of intermediate compartments, d d, and an upper injecting-chamber, e. A pipe, j', conducts the steam by which the mash is heated to the within the compartment b, from which the steam, entering through f, separates whatever can be evaporated. The fresh mash enters the injecting-chamber e through a pipe, l, which is coiled upward within e to be heated by the ascending vapors. This will cause the mash lto enter in a warm state. From the chamber e themash overflows through a pipe, m, tothe compartment d next below, and from .thisfurther down through another overflow-pipe, n,

until it finally arrives in the compartment b, whence it escapes through the pipe h. The steam entering the compartment b through the pipe f ascends, through a central aperture in the lower partitions a; into the lower compartment d, and thence upward through central openings in all the partitions a a. There are caps o o placed inversely over the tubular projections p which surround the central openings in the partitions a. The steam is by the caps crowded down under the surface of the mash in the several compartments, and thereby brought in such intimate contact with the liquid as to evaporate the alcoholic contents of the same. r is asafety-pipe, U-shaped. Itis applied to the top chamber e, and iilled with water to the height of its knee s. The chief characteristic of the mash apparatus A consists, therefore, of the perforated partitions a a, having the pipes p and inversely-arranged caps o, whereby the ascending steam and descending mash are brought into such intimate contact as to be productive of the desired results. Another distinctive characteristic of this mash apparatus consists in the arrangement of the coil l, in which the mash, before entering the chamber e, ascends to be heated. Provision is made for the complete emptying of the chambers d by plugs fitted close to their bottoms. The products of evaporation are, in a pipe, t, carried from the top of the vessel A to the lower part of the column B. This column is also of cylindrical form, and divided, by a series of perforated horizontal partitions, c2 a2 into a lower receiving-chamber, b2, intermediate chambers d2 d2, and a top chamber ez. The alcoholic vapors from the apparatus A enter the chamber b2 through the pipe t, and ascend through the perforated partitions to escape through a top pipe, t2, into the condenser O. Whatever is condensed on the way drops from the several perforated pipes either in drops, or, if it collects in greater masses, through overflow-pipes m2 m2. Under the chamber b2 is another chamber, f2, into which such products of condensation finally escape through a pipe, g2, which is closed by a valve, h2. .Steam is let into the chamber f2 through a pipe, 2, and serves to re-cvaporate such products of condensation, which 'are then, by a pipe, carried back to the lowermost chamber d of the mash apparatus. Z2 is a safety-pipe on the chamber f2. a2 is a pipe which carries products of condensation back to the column B -from the condenser C. The condenser C consists of an outer cylinder, a3, which is illed with water and has a bottom, b3. NVithin the cylinder is a series of upright pipes, d3 d3, whose lower ends lt through the bottom b3, while their upper ends enter a vessel, e3, which connects with the pipe t2. The alcoholic vapors from the column enter the vessel e3, and there pass through a perforated diaphragm, f3, which separates the stream and distributes it for the several pipes d3. In passing through these latter the vapors are exposed to the condensing action of the cold water, and enter finally, together with any products of condensation, a vessel, g, which is aiiixed to the lower end of C, as shown. There is a depression, h3, in the bottom of g3, and a cylinder, i3, open on top, tted into the same. The pipe n2 extends from the outer part of h3. A funnel, j, perforated, is arranged within g3, under the bottom b3, and terminates in a small tube, t3, which enters the cylinder i3, and is open at the bottom. A pipe, m3, extends from the side of the vessel g3 into the cooler D, carrying the vapors to the latter. 'Products of condensation enter the funnel js and ow thence to 3. All the heavy matter overowing from 3 enters the depression h3, and escapes inally, through the pipe n2, into B. The cold water is supplied to the lower part of the vessel al by a pipe, a, from the cooler. The warm Water escapes at top in a pipe, o3. The cooler D consists of a double pipe, a4 L4, which furnishes an annular space, d4, into which the alcohol is conducted by the pipe m3, and whence it is discharged by a pipe, e4. Gold water surrounds and enters the doublepipe a4 b4, and is supplied from belowthrough a pipe, f4, and discharged at the top by the pipe a3. In this cooler the alcohol is fully condensed. The pipe e4 has a suitable lock for collecting and discharging the alcohol. V

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. The coil Z, arranged in the upper chamber e of the mash apparatus' to allow the mash to ascend and become warm before entering the apparatus, as specified.

2. The discharge-pipe h of the mash apparatus, provided with the float-valve j, to be opened only when the spent mash has reached a certain height in the chamber b, as set forth.

3. The cooler D, containing the double pipe a4 b4 and pipe e, as set forth.

4. The combination, in one apparatus, of the vessels A, B, (l, and D, when they are all arranged in the manner substantially as herein shown and described.

The above specification of my invention signed by me this 20th day of November, 1871, at Brieg, in Prussia.
